This tutorial is intended for the Antminer G2 Ethereum Miner of AMD RX570 GPU Miner. This Antminer G2 Ethereum GPU Miner is recently developed by Bitmain, it supports multi-currency mining including ETH, Zcash, XMR and so on. It hits a speed of 220MHash ±10% for ETH mining with EIGHT AMD Radeon RX570 video cards which makes it undoubtedly a pioneer machine in the field.

Operating System	CentOS 7.0 (Linux)
Pre-installed mining software	claymore 9.7
Network Connection	Ethernet
PSU	with PSU

 

Preparations

The following background knowledge would be helpful to use the miner:

• Knowledge regarding GPU and the GPU miners.
• Knowledge regarding how to mine with a PC and how to mine with a video card.
• Knowledge regarding CentOS 7.0 or Linux operating system.
• Knowledge regarding ETH/ETC/ZEC or any others cryptocurrencies coins you are interested.
• Knowledge regarding cryptocurrency such as wallet address, mining pools etc.

 

Miner Connection

• This is the miner you will receive from EastShore.

• A monitor is required (and a keyboard, a mouse) for configuration. (only needed when you configure the miner).
• All the ports needed are on one side of the miner. Those ports are:
  • VGA port: for the monitor connection (HDMI is not supported)
  • USB port x 2: for the keyboard and mouse connection
  • Ethernet port

• Connect your monitor, keyboard, the mouse and the Ethernet cord to the miner.

• Connect the power cable of the PSU.
• Tah-dah, connection done.

 

Start Mining in ONE Minutes

• Power on the miner.

• Wait for 3 ~ 5 minutes, then the operating system will start.
• The mining system of the miner is the “CentOS 7.0” operating system. Generally, the operating system will start automatically, and the Desktop will show.

• However, in some case, there may be an error occurred during the system starting. Don’t worry, just clicking the “Log Out” in the following picture.

• Then click the user “zrt” and input the password “a” to log in.

• If there is a pop-up window titled as “Computers & Contacts” appear after the operating system starts, just close it.

• We will take ETH mining setting as an example in the following tutorial.
• Setting up your own mining account:
  • Open folder “claymore9.7” on the Desktop
  • Right-click on the file “start.sh“
  • Run “Open With gedit“

• The following command  is the ETH mining command

• Set your own mining pool, wallet address and mining worker, then save the changes.

• Close the file, and restart the miner (otherwise the mining settings will not be applied).

• The pre-installed mining software “claymore9.7” will start automatically after 1 minute the operating system restarted.
• However, the “claymore” works as a background program, so the GUI window will not appear. To get the mining details shown, we need to:
  • Open a terminal window on the Desktop
  • Input command: tail -f a.txt
  • Then the mining details will be shown

• You can also use other mining software(should be Linux version) for the mining.

 

Troubleshoot

Q: The hashing speed is lower than usual(eg. 100MH/s for ETH). / There are only 7 (or less) GPU works, not all the eight.

A:

• First, please make sure if all the video cards are working.
  • Right-click on the desktop, click “Open Terminal” on the pop-up menu.
  • In the pop-up windows, input command “lspci | grep -i vga“
  • There should be EIGHT AMD video cards details shown in the windows (it will be showing as “RX 470/480 Series”)

• If there are not EIGHT AMD video cards shown, then maybe some video cards in the case loosened up during shipping.
• In that case, power off the miner first, open the case of the miner to insert those video cards properly and tightly.
• There is a screw on the case of the miner.

• Take the screws out, and slide out the case.

• There are eight video cards in the miner. Please make sure all the cards and cables are inserted tightly.
• Power on the miner again to check if all the video cards appear. The problem would be solved.
